individual throttle bodies

[Guest |109|]

Looking at installing a vi-pec onto a toyota 4age, 20v blacktop ... individual throttle bodies with tuned length intakes and individual air filters ... where would i take the map reading from ?

would it be a case of tapping each of the intake runners and tieing them all together with some 5/16th hose and then back to the map sensor ?

cheers

the AE111 20V runs a map sensor from factory, connect your map sensor of choice to the factory port on the manifold, it's at the timing cover end.

If it's OEM then it might function properly else use the setup you have suggested tying them together to a small canister and connect the MAP sensor to the canister.

Depending on volume of the canister it might dampen the erratic MAP behavior often seen with TB's a bit.

Thanks both.

given this is not quite a factory 20v engine - its also been blueprinted / lightened etc i dont have the 'standard' map port available.

adding the small can would seem to make sense tho.

thanks

How did you get rid of the factory map port? It's machined into the blacktop manifold.

hmm - maybe have found it - looks like its capped off - is it on the top of the inlet manifold, in the middle ?
